C function: getpwuid() which return the struct passwd:

       struct passwd {
           char   *pw_name;       /* username */
           char   *pw_passwd;     /* user password */
           uid_t   pw_uid;        /* user ID */
           gid_t   pw_gid;        /* group ID */
           char   *pw_gecos;      /* user information */
           char   *pw_dir;        /* home directory */
           char   *pw_shell;      /* shell program */
       };

----------------------Code----------------

#include <pwd.h>
register uid_t uid;
struct passwd *uid_pw;
uid = geteuid ();
uid_pw = getpwuid (uid);
strcpy(uname,uid_pw->pw_name)

You can use NSUserName(). This will return the name of the current logged in user.

NSString *userName = NSUserName();
